Magnetic pole
indeterminacy
Cause : It shows the magnetic pole phase could not be
detected after a certain time being passed even
though the process for the magnetic pole phase
detection was executed at the first servo-on after
the power is turned ON.
1) Connector connection error or wire breakage on
an actuator cable.
2) Brake cannot be released on a controller
equipped with a brake.
3) Detection of the motor is not performed properly
because an external force is applied.
4) The slide resistance of the actuator itself is large.
Treatment : 1) Check for the actuator cable wiring condition.
2) Check the wiring condition of the brake cable,
and also turn on/off the brake release switch to
see if the brake makes a “clicking” sound. If the
brake is not making any noise, check if the
power is supplied to the brake properly.
3) Check if there is any abnormality in the parts
assembly condition.
4) It the transportation weight is in the acceptable
range, cut off the power to check the slide
resistance manually by moving with hand.
If the actuator itself is suspected to be the cause,
please contact IAI.

Cold start
Excitement detection
error
Cause : The magnetic pole phase detection is not
completed after a certain time being passed even
though the detection process was executed at the
first servo-on after the power is turned ON.
1) Connection error or wire breakage on an
actuator cable.
2) Brake is not released (when equipped with a
brake).
3) Load to the motor is high due to external force.
4) Power was turned ON while touching to the
mechanical end.
5) The resistance in the actuator sliding operation
is large.
Treatment : 1) Check the wiring condition of the actuator cables.
2) If an improvement can be confirmed when 24V
DC, 150mA is supplied to BKRLS terminal in the
external brake input connector, a malfunction of
the controller can be considered. Please contact
IAI.
3) Confirm that there is no error in the mechanical
part assembly condition.
4) Move the slider or the rod to a point where it
would not hit the mechanical end and reboot the
system.
5) If the loaded weight is within the allowable
range, turn the power OFF and check the
resistance in sliding operation by moving the
slider with hand.
